Production of new antioxidant compound from mycosporine-like amino acid, porphyra-334 by heat treatment.
Abstract In this study, we evaluated the antioxidant activity (diphenylpicrylhydrazyl (DPPH)-radical scavenging activity) of the low-molecular weight fraction of water-soluble Susabinori ( PorphyraExpand
Gastrointestinal enzyme production of bioactive peptides from royal jelly protein and their antihypertensive ability in SHR.
The gastrointestinal enzyme production of antihypertensive peptides from RJ was reported here to clarify the potential physiological function of royal jelly and to find a good resource of ACE inhibitory peptides produced by the gastrointestinal enzyme hydrolyses. Expand
α-Glucosidase Inhibitory Action of Natural Acylated Anthocyanins. 2. α-Glucosidase Inhibition by Isolated Acylated Anthocyanins
Four diacylated pelargonidin (Pg:  SOA-4 and SOA-6), cyanidin (Cy:  YGM-3), and peonidin (Pn:  YGM-6) 3-sophoroside-5-glucosides isolated from the red flowers of the morning glory, Pharbitis nil cv.Expand
Latent production of angiotensin I‐converting enzyme inhibitors from buckwheat protein
BW proteins offer a potential resource for producing ACE inhibitory peptides during the digestion process, and a single oral administration of BW digest lowered the systolic blood pressure of a spontaneously hypertensive rat. Expand
Comparison of the WST-8 colorimetric method and the CLSI broth microdilution method for susceptibility testing against drug-resistant bacteria.
The results suggest that the WST-8 colorimetric assay is a useful method for rapid determination of consistent MICs for drug-resistant bacteria. Expand
α-Glucosidase Inhibitory Profile of Catechins and Theaflavins
To clarify the postprandial glucose suppression effect of flavonoids, the inhibitory effects of catechins and theaflavins against alpha-glucosidase (AGH) were examined in this study. It was initiallyExpand
Anti-hyperglycemic effect of diacylated anthocyanin derived from Ipomoea batatas cultivar Ayamurasaki can be achieved through the alpha-glucosidase inhibitory action.
No significant change in BGL was observed when sucrose or glucose was ingested, suggesting that the anti-hyperglycemic effect of the anthocyanin was achieved by maltase inhibition, not by sucrase or glucose transport inhibition at the intestinal membrane. Expand
Strong antihyperglycemic effects of water-soluble fraction of Brazilian propolis and its bioactive constituent, 3,4,5-tri-O-caffeoylquinic acid.
Among the active compounds isolated from the fraction, 3,4,5-tri-caffeoylquinic acid was found to be a prominent candidate that exerts the effect and shows a strong maltase-specific inhibition with an IC(50) value of 24 microM. Expand
Val‐Tyr As A Natural Antihypertensive Dipeptide Can Be Absorbed Into The Human Circulatory Blood System
1. Intact absorption of the bioactive dipeptide Val‐Tyr (VY), with in vivo antihypertensive ability in normotensive human subjects, was investigated.
alpha-Glucosidase inhibitory profile of catechins and theaflavins.
It is demonstrated for the first time that TF-3-O-Gal can suppress glucose production from maltose through inhibition of AGH in the gut through the effects of catechins and theaflavins against alpha-glucosidase. Expand
